He'll miss at least the next four weeks. Kumerow already missed a big chunk of time earlier this season with an ankle injury, then either suffered a new one or re-aggravated the old one in Week 10. We don't think any of you were holding on to hope in fantasy leagues, but if you were, this looks likely to be the end of the line for him this year. 

He was quickly ruled out. Kumerow missed several weeks with an ankle injury earlier this season, but it's not currently known if the injury is an aggravation or not. 

He wasn't close to practicing all week and now has missed six consecutive practices. The Bills haven't placed the backup outside wideout and special-teamer on injured reserve yet, but he's quickly closing in on the amount of weeks he would have been mandated to miss on it. There is no positive trendline yet for Week 6. 

He has not practiced for five-straight sessions since injuring his ankle in Week 3. Kumerow will likely continue to sit this weekend at this point. Gabe Davis and Isaiah McKenzie (concussion) will be the main supporting weapons for Josh Allen this weekend against the Steelers.
